<h3><span class="yiyi-st" id="yiyi-77">为什么有不止一种数据结构?</span></h3>
<p><span class="yiyi-st" id="yiyi-78">学习 pandas 数据结构的最好方法是将其作为低维数据的灵活容器。</span><span class="yiyi-st" id="yiyi-79">例如，DataFrame 是 Series 的容器，Panel 是 DataFrame 对象的容器。</span><span class="yiyi-st" id="yiyi-80">我们希望能够以类似字典的方式从这些容器中插入和删除对象。</span></p>
<p><span class="yiyi-st" id="yiyi-81">此外，我们将对通用API函数（其考虑时间序列和横截面数据集的典型取向）采取明智的默认行为。</span><span class="yiyi-st" id="yiyi-82">当使用ndarrays存储2维和3维数据时，用户在编写函数时会考虑数据集的方向，轴被认为或多或少相等（除非C-或Fortran连续性对性能至关重要）。</span><span class="yiyi-st" id="yiyi-83">在pandas中，轴旨在为数据提供更多的语义意义；即，对于特定数据集，可能存在定向数据的“正确”方式。</span><span class="yiyi-st" id="yiyi-84">因此，目标是减少在下游功能中编码数据转换所需的精神努力量。</span></p>
<p><span class="yiyi-st" id="yiyi-85">例如，对于表格数据（DataFrame），考虑<strong>索引</strong>（行）和<strong>列</strong>而不是轴0和轴1更具语义上的帮助。</span><span class="yiyi-st" id="yiyi-86">并且遍历DataFrame的列，因此导致更可读的代码：</span></p>

<p><span class="yiyi-st" id="yiyi-88">所有的pandas数据结构都是值可变的（它们包含的值可以改变），但不总是size-mutable。</span><span class="yiyi-st" id="yiyi-89">Series的长度不可更改，但是，可以将列插入到DataFrame中。</span><span class="yiyi-st" id="yiyi-90">然而，绝大多数方法产生新对象并且保持输入数据不变。</span><span class="yiyi-st" id="yiyi-91">一般来说，我们喜欢<strong>有利于不变性</strong>。</span></p>
